To solve this expression, we can follow the order of operations (PEMDAS).
First, let's simplify the multiplication and division.
(-4) x (7/5) x (-3/4) ÷ (7/15)
=(-4) x (-7/5) x (-3/4) ÷ (7/15)
Now, let's multiply the numbers together.
=(-4)(-7)(-3)/(5)(4)(7)/(15)
=84/20/7/15
Next, let's simplify the division by multiplying by the reciprocal.
=(84/20)(1/7)(15/1)
= (84/20)(15/7)
= (84)(15)/(20)(7)
= 1260/140
= 9
Therefore, the answer is A. 9.
use the properties of operations and rules for multiplying and dividing signed numbers to solve:
(-4) x (7/5) x (-3/4) ÷ (7/15).
